You can import items such as VM templates and vApps to a content library from your local machine or from a Web server, and use them to create virtual machines and vApps. You can also import ISO images, certificates, and other files, which you want to keep in the library and share with other users across multiple vCenter Server systems.

You can clone existing vApps to vApp templates in a content library. You can use the vApp templates later to provision new vApps on a cluster or a host in your vSphere inventory. The vApp is exported to a content library in the OVF format.

You can clone virtual machines or VM templates from your vCenter Server inventory to templates in the content library and use them later to provision virtual machines on a cluster or a host. You can also clone a virtual machine or VM template to update an existing template in the library.
